Book Description
This project investigated the seasonal behavior of integral abutment bridges through field monitoring and finite element modeling (FEM). The Orange-Wendell Bridge was used as a case study for the project. The structure was instrumented with 85 gages measuring bridge movements and forces (temperature gages, joint meters, tilt meters, strain gages, earth pressure cells, thermistors and four inclinometer casings for manual readings). Instruments were monitored by the University of Massachusetts at Amherst from January 2002 through December 2004. Both 2-D and 3-D FEM of the bridge were developed using GTSTRUDL and calibrated to the field data. Parametric FEM was performed to evaluate the influence of soil properties and construction practices on bridge behavior.

Book Description
Integral abutment (IA) construction has become the preferred method over conventional construction for use with typical highway bridges. However, the use of these structures is limited due to state mandated length and skew limitations. To expand their applicability, studies were implemented to define limitations supported by rational analysis rather than simply engineering judgment. Previous research investigations have resulted in larger length limits and an overall better understanding of these structures. However, questions still remain regarding IA behavior; specifically questions regarding long-term behavior and effects of skew. To better define the behavior of these structures, a study was implemented to specifically investigate the long term behavior of IA bridges. First, a field monitoring program was implemented to observe and understand the in-service behavior of three integral abutment bridges. The results of the field investigation were used to develop and calibrate analytical models that adequately capture the long-term behavior. Second, a single-span, quarter-scale integral abutment bridge was constructed and tested to provide insight on the behavior of highly skewed structures. From the acquired knowledge from both the field and laboratory investigations, a parametric analysis was conducted to characterize the effects of a broad range of parameters on the behavior of integral abutment bridges. This study develops an improved understanding of the overall behavior of IA bridges. Based on the results of this study, modified length and skew limitations for integral abutment bridge are proposed. In addition, modeling recommendations and guidelines have been developed to aid designers and facilitate the increased use of integral abutment bridges.

Book Description
The objective of this project was to revise and make more accurate integral abutment bridge design criteria based on observed structural behavior and results of numerical parametric studies. Observed behaviors were on the basis of field monitoring conducted at 4 integral abutment bridge sites and a weather station utilizing previously installed instrumentation and data acquisition systems. Integral abutment bridge engineering data were continuously collected over the entire contract period at bridges 109, 203, 211, and 222 and compiled, processed and evaluated. Numerical parametric studies were conducted on the basis of 2D and 3D finite element models, developed and calibrated to the observed integral abutment behavior, in order to evaluate the field performance of integral abutments and establish the range of potential applications for integral abutment bridge construction in Pennsylvania.

Book Description
Although integral abutments bridges have been used successfully for 50 years, there are no uniform standards or policies regarding permissible bridge lengths, skews, details or design procedures. Their implementation is not an exact science, but rather a matter of intuition, experimentation and observation. Analysis and Design of Integral Abutment Bridges five-part treatment starts with a clear and rigorous with the types of Integral Abutment Bridges their common problems and code applications. This is quickly followed by applications for analytical methods and computer software including Lateral Load Analysis Techniques and Nonlinear Analysis of Integral Abutment Bridges. Next, the third part on the Methods of Design and Structural Details includes Foundations, Backfill and a section on Beam Design including steel, cast-in-place concrete beams and precast/prestressed concrete beams. With this book in hand, structural and bridge engineers will find a brief and valuable guide illustrating how these concepts are successfully applied in the real world. The latest published results on experimental, analytical, and field studies on the behaviour of integral abutment bridges and their components Unified guidelines based on activities such as the AASHTO/NCHRP joint taskforce, LRFD specs and FHWA-sponsored research study on Jointless Bridges The book contains sufficient coverage of the most critical behavioural aspects of integral abutment bridges, namely: Interaction between the foundation piles, the integral abutment, and the surrounding ground under cyclic loading due to temperature effects, dynamic earthquake loading, and shrinkage/creep Abutment displacements and associated earth pressure distribution Settlement of the approach fill
